How To Reduce Your Carbon Footprints On Earth.

          In facing the growing challenge of globalization, there are some major problems being faced by our planet. Earth is the only planet that can serve as a home for us and future generations. But we do not realize that everything we do from watching television until driving a car can contribute to a warmer earth. We all have our own responsibility to take a good care on it. But, are we doing good enough to take care of the environment and the earth? There are a lot of steps to reduce the carbon footprint on the earth.

          First and foremost, the use of air conditioners practically mandatory. Good in homes, offices, shopping malls and so on. AC or air conditioners are very useful for people who live in areas with warm climates, including Malaysia. This is why most people in this world love the cold air by installing the air conditioner every 24 hours. To overcome this problem, we can reduce the uses of air conditioners with replaces it with fans or open the window for sometimes to let the fresh air in.

          Furthermore, to reduce the carbon footprints on our earth, we can take public transit or public transportation or carpool instead. According to The Rideshare Company, the average American spends 18 days of the year in a car, each car emitting its own weight in carbon dioxide. The benefits of carpooling are quite simple to see. One car uses less gas than two and much less than three. Similarly, riding the bus or train to work helps to slash down the number of cards on the road.

          In addition, carbon can be reduced by planting the trees that been felled. Replanting of trees is important because plants absorb carbon dioxide and release oxygen to other life. Instead of animal and human release of carbon dioxide needed by plants in photosynthesis. Plants filter out most of the dust in the air and absorb cash receipt dioxide gas and thus help control air pollution. The most important is, that the plants can protect the surface from direct sunlight, reducing evaporation of water and help cool the earth's surface.

          One source contributor of carbon dioxide is the burning of fossil fuels. The use of fossil fuels began to increase rapidly since the industrial revolution in the 18th century. At that time, coal became the dominant energy source for later replaced by oil in the mid-19th century. In the 20th century, gas started to be used as an energy source. Change of trend in the use of fossil fuels is actually indirectly reduce the amount of carbon dioxide released into the air, as gas releases less carbon dioxide than oil and much less than coal. Nevertheless, the use of renewable energy and nuclear energy further reduce the release of carbon dioxide into the air. Nuclear energy, although controversial for reasons of safety and hazardous waste, does not emit any carbon dioxide at all.

The Importance Of Water

          Water brings and sustains life on our planet. Water is something which we cannot do without only when it is not available. After all, our bodies are made up of seventy percent water. It is quite possible to survive without food for more than a month, but without water we will perish in a matter a days. Remember the ancient mariner's cry of agony and despair in Samuel Taylor Coleridge's poem?

Water, water, everywhere,
And all the boards did shrink,
Water, water, everywhere,
Nor any drop to drink.

          This verse of the poem clearly points to the absolute need of suitable drinking water of survival. The mariner, being the only survivor left on his ship, is desperately lost at sea for months. Having used up all the ship's store of drinkable water, he laments on his plight: surrounded by water on all sides, but not a drop of drink!

          Water is essential to life. We required water for washing and cooking, cultivating our fields and most importantly for drinking. Life becomes impossible on earth without water. Imagine a drought situation, there are no rains, the river and lakes have dried up and all planet life lay dry and wasted. In such situation, the Grim Reaper becomes exceedingly busy, for water is life giving and every living organism, without exception, requires water of its existence. Dehydration spells, without mistake, certain, inescapable death.

          When we read about the origins of life in this planet, we realize at once the important role water had played in causing living things to come into existence. Life began, or so geologists and scientists say, in the watery oceans. Water has those unique chemical elements and properties needed to nourish the living cells of living beings.

          Apart from the glaringly obvious fact that water is essential to life, water is also man's important precious resource. Water is source of energy. Water converted into steam can be used as fuel for driving vehicles fitted with the steam engines. Electricity can also be generated with hydro power. In fact, about a third of the world's electricity comes from hydroelectric power plants. And this form of power supply is cheap since water is free, and running costs of hydroelectric power plants in much cheaper compered to the other types of power plants.

          The importance of water can in no measure be minimized. It is not only a source of life and energy, it also sustains life on the planet. We should all be duty bound to ensure that our sources of water remain unpolluted.
